Recent Exploration Successes and Upcoming Catalysts in the Llanos Basin in Colombia (Graphic: Business Wire)

Oil and Gas Production Back Online

• GeoPark is currently producing approximately 39,000 boepd¹
• 3Q2023 consolidated average oil and gas production of 34,778 boepd, below its potential mainly due to temporarily shut-in production in the CPO-5 block (GeoPark non-operated, 30% WI) in Colombia and in the Fell block (GeoPark operated, 100% WI) in Chile
• 12 rigs currently in operation (7 drilling rigs and 5 workover rigs), including 5 drilling rigs on exploration and appraisal wells

Colombia - Llanos Basin: New Exploration Success and Drilling High-Potential Prospects

Llanos 34 Block (GeoPark operated, 45% WI):

• The third horizontal development well initiated testing in early October 2023 and is currently producing approximately 1,800 bopd from the Mirador formation
• GeoPark has already spudded the fourth and fifth horizontal wells, which are expected to reach total depth in November 2023
• The block is currently producing approximately 54,200 bopd gross (vs 53,367 bopd gross in 3Q2023)

CPO-5 Block:

• The operator spudded the Halcon 1 exploration well in late September, targeting the exploration potential of the Guadalupe formation in the northern part of the CPO-5 block, close to the southern part of the Llanos 34 block, expected to reach total depth in late October 2023
• In late September 2023, the operator received approval from the regulator (ANH) to resume production in the Indico 6 and Indico 7 wells², which are currently producing 7,500-8,000 bopd gross in aggregate. These wells could potentially increase and stabilize their combined production at approximately 9,000 bopd gross before year-end, depending on reservoir performance

Breakdown of Quarterly Production by Country

The following table shows production figures for 3Q2023, as compared to 3Q2022:

Quarterly Production

Oil and Gas Production Update

Consolidated:

Oil and gas production in 3Q2023 was 34,778 boepd, down by 9% compared to 3Q2022, due to lower production in Colombia, Chile, Brazil and Ecuador. Oil represented 93% and 91% of total reported production in 3Q2023 and 3Q2022, respectively.

GeoPark is currently producing approximately 39,000 boepd⁵.

Colombia:

Average net oil and gas production in Colombia decreased by 5% to 31,780 boepd in 3Q2023 compared to 33,338 boepd in 3Q2022, mainly resulting from lower production in the Llanos 34 and CPO-5 blocks, partially offset by higher production in the Platanillo block (GeoPark operated, 100% WI) and to a lesser extent, new production coming on in the Llanos 123 block.

Oil and gas production in GeoPark’s main blocks in Colombia:

• Llanos 34 block net average production decreased by 7% to 24,015 bopd (or 53,367 bopd gross) in 3Q2023 compared to 3Q2022, mainly due to the natural decline of the fields and to a lesser extent temporary local blockades that partially affected production and operations for 10 days
• CPO-5 block net average production decreased by 10% to 5,063 bopd (or 16,877 bopd gross) in 3Q2023 compared to 3Q2022. Production in 3Q2023 has been below its potential due to shut-ins of the Indico 6 and Indico 7 wells, which are currently producing approximately 7,500-8,000 bopd gross in aggregate. These two wells could potentially increase and stabilize their combined production at approximately 9,000 bopd gross before year-end, depending on reservoir performance
• Platanillo block average production increased by 35% to 2,027 bopd in 3Q2023 compared to 3Q2022
• Llanos 123 block net average production was 313 bopd (or 626 bopd gross) in 3Q2023, reflecting partial production from the Saltador 1 exploration well that initiated testing during the quarter

Recent Activity in the Llanos Basin

Llanos 34 Block

• The third horizontal development well initiated testing in early October 2023 and is currently producing approximately 1,800 bopd from the Mirador formation
• GeoPark has already spudded the fourth and fifth horizontal wells, which are expected to reach total depth in November 2023

CPO-5 Block

• The operator spudded the Halcon 1 exploration well in late September, targeting the exploration potential of the Guadalupe formation in the northern part of the CPO-5 block, close to the southern part of the Llanos 34 block
• Preliminary activities are underway to acquire over 230 square kilometers of 3D seismic, expected to be executed in early 2024
• This 3D seismic acquisition is expected to add additional exploration prospects to GeoPark’s organic exploration inventory

Llanos 123 Block

• The Toritos 1 exploration well reached total depth in September 2023
• Logging information indicated hydrocarbon potential in the Barco (Guadalupe) and Gacheta formations
• Testing activities initiated in late September 2023, and the well is currently producing approximately 1,370 bopd of 14 degrees API with a 1.5% water cut from the Barco (Guadalupe) formation
• The Saltador 1 exploration well, which started testing in July 2023, was the first exploration success in the Llanos 123 block and continues producing approximately 760 bopd of 16 degrees API with a 4% water cut from the Barco (Guadalupe) formation
• Based on these positive results, on October 12, 2023, GeoPark spudded a new exploration well, Bisbita Centro 1, targeting an exploration prospect located 1.5 km south of the Saltador 1 well

Llanos 87 Block

• GeoPark spudded the Zorzal Este 1 exploration well on October 5, 2023, and it is expected to reach total depth in early November 2023

Llanos 124 Block (GeoPark operated, 50% WI-Hocol 50% WI):

• Cucarachero 1 exploration well reached total depth in August 2023
• The well encountered reservoir in the Cuervo formation with no evidence of hydrocarbons

Llanos 86 and Llanos 104 Blocks (GeoPark operated, 50% WI-Hocol 50% WI):

• The Llanos 86 and Llanos 104 blocks are adjacent to the eastern side of the CPO-5 block
• Preliminary activities are underway to acquire over 650 square kilometers of 3D seismic, expected to be executed in early 2024
• This 3D seismic acquisition is expected to add additional exploration prospects to GeoPark’s organic exploration inventory

Ecuador:

Average net oil production in Ecuador before the Government’s share decreased 45% to 659 bopd in 3Q2023, (approximately 465 bopd after the Government’s share), compared to 1,194 bopd in 3Q2022, mainly due to the natural decline of the fields.

Ecuador is currently producing approximately 2,400 bopd gross, following the successful drilling and testing of the Yin 2 and the Perico Centro 1 wells.

The Government’s production share varies with oil prices and is approximately 30-40%, considering an Oriente crude oil price of $70-100 per bbl.

Recent Activity in the Perico Block

• The Perico Centro 1 exploration well reached total depth in September 2023
• Preliminary logging information indicated hydrocarbon potential in the U-sand formation
• The well initiated testing in late September 2023 and is currently producing approximately 830 bopd of 28 degrees API with a 1% water cut
• The Yin 2 well started production tests in mid-August 2023 and is currently producing approximately 740 bopd of 30 degrees API with a 1% water cut from the U-sand formation
• Based on these positive results, on October 8, 2023 the operator spudded a new appraisal well, the Perico Norte 4, which is expected to reach total depth in late October 2023

Chile:

Average net production in Chile decreased 35% to 1,565 boepd in 3Q2023 compared to 2,425 boepd in 3Q2022, resulting from the natural decline of the fields, limited drilling activities and temporarily shut-in oil production due to commercial negotiations. GeoPark reached an agreement with the oil off-taker and as of August 2023 it gradually started reopening temporarily shut-in oil production of 400 bopd.

The production mix was 89% natural gas (vs 84% in 3Q2022) and 11% light oil (vs 16% in 3Q2022).

Brazil:

Average net production in the Manati field (GeoPark non-operated, 10% WI) in Brazil decreased 46% to 774 boepd in 3Q2023 compared to 1,439 boepd in 3Q2022. Production in Manati was temporarily interrupted for 24 days during 3Q2023 due to lower gas demand. Production restarted in late September 2023 and the Manati field’s net production is approximately 1,550 boepd.

The production mix was 99% natural gas and 1% oil and condensate in both 3Q2023 and 3Q2022.
